The first sustained hot stretch in the San Gabriel Valley does more than send everyone to the pool. Water heaters work harder, hose bibs and supply lines expand and contract, and slab plumbing shifts slightly in the heat. Some problems that stayed invisible in mild weather show up all at once.
Drain Doctor Plumbing & Rooter has handled summer plumbing calls across Covina, West Covina, Glendora, and Walnut since 1996. Here is what to check when temperatures climb.
Water heater strain
More showers, heavier laundry, and higher incoming water temperatures push water heaters harder in summer. If hot water runs out faster, the temperature fluctuates, or you hear popping from the tank, schedule water heater repair before the unit fails completely.
Sediment buildup in older tanks reduces efficiency and can cause overheating. Flushing and inspection are worth scheduling before peak summer demand.
Hose bibs and outdoor supply lines
Check outdoor faucets for drips when you first turn them on for the season. A hose bib that leaked over winter may have wasted water unnoticed. Leaks at outdoor connections also indicate supply line wear that plumbing repair can address before a burst.
Slab leaks and supply line stress
Homes on slab foundations, common across the San Gabriel Valley, can develop pinhole leaks in copper supply lines as soil and concrete shift with temperature changes. Signs include unexplained increases in your water bill, warm spots on the floor, or the sound of running water when everything is off.
If you suspect a slab leak, call promptly. Early detection limits water damage. Read our guide on detecting hidden water leaks for more warning signs.
Drains and main lines in summer
Heat does not cause drain clogs directly, but summer habits do: more disposal use from fresh produce, more laundry, and houseguests all add volume. A line that barely kept up in spring may clog in July. Schedule drain clearing at the first sign of slow drainage rather than waiting for a backup.
When to call
Call when you notice water heater problems, unexplained water bill increases, outdoor leaks, or slow drains that persist more than a day. We offer same-day service and 24/7 emergency response across the San Gabriel Valley.
